The reason a burned out bulb will cause the a rapid flashing has to do with the way the relay works (Part #100708). It is like flashing Christmas tree lights. When a certain amount of current is flowing, a bi-metal strip in the relay will heat up and curl away from the contact which disengages the circuit. When it cools down, the metal straightens out again, current flows and the process begins again. When a bulb is burned out there is less resistance to the flow of current which causes the metal strip to heat up quicker so you get the faster flashing. Having said that the problem is either in the flasher relay or there is less resistance in the circuit that it was designed for. It could be something as simple as the wrong bulb(s).
